Microsoft.Extensions.Caching.Memory 9.0.9

About

Provides implementations for local and distributed in-memory cache. It stores and retrieves data in a fast and efficient way.

Key Features

A concrete implementation of the IMemoryCache interface, which represents a local in-memory cache that stores and retrieves data in a fast and efficient way
A distributed cache that supports higher scale-out than local cache
Expiration and eviction policies for its entries
Entry prioritization for when the cache size limit is exceeded and needs to be compacted by entry eviction
Track of cache statictics

How to Use

Use Microsoft.Extensions.Caching.Memory over System.Runtime.Caching when working with ASP.NET Core as it provides better integration support. For example, IMemoryCache works natively with ASP.NET Core dependency injection.

Local in-memory serialization:

using Microsoft.Extensions.Caching.Memory;

using MemoryCache cache = new(new MemoryCacheOptions());

object valueToCache = new();
string key = "key";

using (ICacheEntry entry = cache.CreateEntry(key))
{
    // Entries are committed after they are disposed therefore it does not exist yet.
    Console.WriteLine($"Exists: {cache.TryGetValue(key, out _)}\n");

    entry.Value = valueToCache;
    entry.SlidingExpiration = TimeSpan.FromSeconds(2);
}

bool exists = cache.TryGetValue(key, out object? cachedValue);
Console.WriteLine($"Exists: {exists}" );
Console.WriteLine($"cachedValue is valueToCache? {object.ReferenceEquals(cachedValue, valueToCache)}\n");

Console.WriteLine("Wait for the sliding expiration...");
Thread.Sleep(TimeSpan.FromSeconds(2));

Console.WriteLine("Exists: " + cache.TryGetValue(key, out _));

// You can also use the acceleration extensions to set and get entries
string key2 = "key2";
object value2 = new();

cache.Set("key2", value2);

object? cachedValue2 = cache.Get(key2);
Console.WriteLine($"cachedValue2 is value2? {object.ReferenceEquals(cachedValue2, value2)}");
